A new stadium the Raiders are proposing for Oakland would cost some $800 million—and after the team and the NFL contribute, $300 million would still be needed to build it, according to the Oakland Tribune. The Raiders’ lease with Oakland and Alameda County expires after this season.

The Tribune reported Tuesday that a consultant hired by the team told the city and county joint board that runs O.co Coliseum, that the Raiders would put $300 million into the stadium, and the NFL would likely put in $200 million from its stadium loan program.

The balance, David Stone of AECOM told the board, would have to be made up with public money—a problem that Oakland city councilman Larry Reid told the Tribune acknowledged, with the departure of the NBA’s Golden State Warriors to San Francisco and the baseball Oakland Athletics’ discussions about moving to San Jose in motion.

"My primary concern is this is a city that always had three major league teams and that now there is the possibility that we will have none," Reid told the Tribune.

Raiders owner Mark Davis has said that he wants to keep the team in Oakland, but does not want to sign another short-term lease at the Coliseum without an agreement in place for a new stadium. The Raiders returned from Los Angeles in 1995, after 13 years away from their original home, and the stadium deal between the team and city and county has been a point of contention and acrimony ever since.

"There is no set deadline ... but we know time is not on our side, even if there isn't a deadline," Assistant City Administrator Fred Blackwell told the Tribune.

The proposed Raiders stadium would have a capacity of 50,000, smaller than any currently in use in the NFL.

In a statement, Raiders director of public affairs Mike Taylor said, "Both sides are conducting studies to determine the demand and financial viability of the project." No team official was present at the meeting, the Tribune said.

The San Francisco 49ers’ new stadium to the south, in Santa Clara, has a current price tag of $1.3 billion; about two-thirds of that will be paid for by a loan taken out by the county, and the NFL will contribute some $200 million from the same stadium loan program suggested by Stone. Talks about the Oakland Raiders and 49ers sharing a stadium never gained much traction.
